HARVESTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 398,711, dated February 26, 1889.

Application filed October 18, 1886. Serial No. 216,597. (No model.)

' of which the following is a specification.

My invention relates to certain improvements in the running-gear for harvesting-machines of that class in which the header and thrasher are connected together and hauled 1 about the field, the grain beingcut, thrashed, l

separated, and cleaned during the operation.

My invention consists in certain improvements in the turn-table an d single front wheel upon which the front portion of the machine is supported.

These improvements will be more fully explained by reference to the accompanying drawings, in whichlrigure 1 is a plan View of the front wheel and the turntable. Fig. 2 is a side elevation of the same. Fig. 3 is a detail of the hoop or band ll, showing its extensions 13 and the transverse beam C. Fig. l is a detail of the inner ring, G. Fig. 5 is a sectional view through the two rings B and G.

C C are the sills of the thrashin gmachine. I have only shown the front ends of these sills, because that all that is necessary to illustrate the present invention.

C is a transverse beam fixed to the front end of the sills at right angles thereto.

15B is an iron hoop or band, made of suitable vertical. depth, and having rearward extensions B" welded thereto and bolted to the inner sides of the sills C C, along which they extend, as shown in Figs. 1. and 3. The rear portion, 13, of the ring, which forms a continuation and part of the complete ring, has countersunk bolt'holes made in it, through which bolts to pass for the purpose of securing this portion of the ring firmly to the transverse beams C. In this manner this ring is made very strong and held firmly in place, so as to prevent any springing or twisting out of shape.

The inner movable ring, (his made of similar shape and depth with the outer ring and of sufficiently smaller diameter to turn freely within it, and said inner ring is provided with inwardly-projecting lugs u, as shown in Figs. 1, at, and Beneath this inner ring are the iron plates D, extending fore and aft, and having the central portion bent downward to form an attachment for the journal-boxes H of the front wheel, A, the shaft of which is supported in the boxes H, as shown. Across the top of the ring G, and directly above the angular plates D, are the straightiron plates D. These plates D and D extend beyond the periphery of the outer ring, B B, at front and rear, and they are secured to the inner ring, G, and also to each other by bolts I, which pass through the lugs w on the inside ring, as shown'more particularly in Fig. 5. The angular plat s D thus support the weight of the front end of the machine, while the plates I) extend above the upper edge of the ring B and serve as a guide to steady the inner ring, G, and the wheel A as they are turned from side to side within the outer ring. The front ends of the plates D are provided with eyes J, and the tongue E has corresponding eyes, through which the long bolt K passes to attach the tongue to the turn-table.

It will be manifest that when the tongue is turned from side to side by the movement of the team which hauls the machine the inner ring, G, and the bearing-wheel A will be correspondingly turned, so as to change the direction of the travel of the machine. The surface of the bearin g-wheel A is made smooth, so as to allow it to slip to one side in turning sharp corners, as when the machine is driven into a corner and then turned at right angles with its former course.

I am aware that the single front wheel has been used before, and I do not claim this, broadly; but

What I do claim as new, and desire to se cure by Letters Patent, is-

1. The combination, with the sills C and the transverse beam C, of the exterior ring, B B, having the extensions 13' welded thereto and secured to said sills, the bolts a, passing through the rear of said ring and securing it to the transverse beam, and an inner ring within the outer ring, substantially as herein described.

2. The combination of the outer stationary ring, B B, secured to the sills C and trans verse beam 0 of the frame, the inner ring, G, turning within the outer one, the plates D, secured to the top of the inner ring and eX- tending beyond the edges of the enter one, and the angular plates 1), secured to the b0t- Witnesses:
